Zion YETI 5/4 Chest Zip Steamer Wetsuit - Black

Zion YETI 5/4 Chest Zip Steamer Wetsuit - Black

The Zion YETI 5/4 Chest Zip Steamer Wetsuit in Black is built for surfers who need maximum warmth, sealed construction and proper cold-water performance. Designed for the rougher end of winter surf, this suit brings together heavy-duty insulation, flexible movement and Zion’s premium YETI build quality.

The 5/4mm thickness gives serious cold-water protection when a 4/3mm steamer is not quite enough. It is made for freezing dawn patrols, windy winter sessions, long cold-water paddles and southern surf conditions where warmth is the difference between staying out and calling it early.

The chest zip entry gives the suit a secure upper-body fit while helping reduce flushing through the neck and shoulders. Zion’s YETI construction uses 100% S-Seal external liquid taping to help minimise water entry through the seams, while the superstretch Japanese limestone-based neoprene keeps the suit moving properly despite the added winter thickness.

Inside, the YETI range features Pure Yeti Wool lining through the chest and back for added warmth, with Bamboo Charcoal internal jersey through the arms and lower legs for comfort and movement. The glideskin neck, interior wrist and ankle grips, and tradie-approved key stash make it a proper cold-water surf suit with practical detail where it counts.
